Editor's Note: Curcumin Potentiates the Antitumor Effects of Bacillus Calmette-Guerin against Bladder Cancer through the Downregulation of NF-κB and Upregulation of TRAIL Receptors

The editors are publishing this note to alert readers to a concern about this article (1). It appears that the same image was used to represent 4% curcumin treatment in control medium and in combination with PMN in Fig. 1A and another image was used to represent curcumin treatment and BCG treatment in Fig. 5B. Following an institutional review, the original research records related to the figures did not sufficiently address these concerns. Therefore, the institution was not able to determine the relation of the images to the experiments described.
